1. Positive rake angle implies the sum of the clearance angle and wedge angle is less than 90°.
2. Negative rake offers a strong tooltip, which makes the tool more resilient under impact loading.
3. Zero rake angle is in between the positive and negative rake angles. It can provide advantages of both of them; however, to some extent. Cutting tool with zero rake angle is easy to design and manufacture. Such tools also provide advantage while re-sharpening the tools. Thread cutting tools are usually provided with zero rake angle.
